Absolutely Stunning Fighter

It has taken a very long time to come this stage. When any project takes more than 10 years, the requirements change. I sincerely hope that the LCA fulfils all the expectations.

IMO engine and the avioics suite is still a question mark. On paper it does look good.
 
The finishing the making of lca by the contribution of french who gave them technology for cutting the parts of this Jet

your ignorance is blinding me with its brilliance

the design and manufacturing of the composite material [45% of the Tejas is made from composite material] is performed with the help of the AutoLay, a software technology developed indigenoulsy by the Aeronautical Development Agency

I also found it funny that you are not aware of the fact that composite materials products are prepared by additive manufacturing process, meaning there is no "cutting" in composite materials.

The process of laying out the composite fibres in a particular orientation to achieve the desired structural rigidty is done manually aided by the autolay software, before being put inside the autocalve for hardening/curing

Not only did India not recieve the technology for the composite material body, on the other hand India is exporting this very indegenously developed technology to the Frenchmen

Thursday , February 27, 2003 EIGHT YEARS OF R&D IN AIRCRAFT technologies finally paid off when a slim, fighter jet took to the skies. But even better, spin-off technologies from the development of the world's lightest combat aircraft are poised to fund further research in defense.

The Light Combat Aircraft (LCA), India's first fully indigenous and the world's smallest combat aircraft. The machine graduated from a mere concept to a flying machine on January 4, 2002. When Wing Commander Rajiv Kothiyal, a test pilot of the Indian Air Force taxied and took off, pundits lauded the flight as “sheer poetry in motion.”

But, overshadowed by the euphoria over the first flight of the LCA, a revolution is quietly brewing. Some time in 2000, the Defense Research Development Organization, an umbrella organization that consists of 51 laboratories, decided to license spin off technologies—corollaries to the actual task of building the world's smallest combat aircraft. As a first step, the CAD software—Autolay—developed by scientists at the Aeronautical Development Agency (ADA), the nodal agency for the LCA, was earmarked for licensing.

ADA announced that its flagship software product, Autolay, would be licensed to commercial aircraft maker Airbus Industrie for $3.2 million for use in its new commercial super jumbo project: A 380.

The contract was the culmination of a long-drawn and extensive benchmarking by Airbus Industrie to select composites software for the A380 project. The contract marked a first of sorts. At a time when governments around the world were being forced to cut down on defense expenditure, India was having its own defense R&D expenditure being subsidized by the sale of spin-off technologies. The Airbus contract was sourced through the marketing expertise of U.S.-based CAD/CAM major Parametric Technology Corporation (PTC). Says Air Marshall (retd.) Philip Rajkumar (PVSM), director of the ADA, “While our R&D expertise is second to none, we had no marketing muscle. It made sense to approach a company with proven competencies in this field.” Interestingly, ADA subsequently handed over Autolay along with the associated Intellectual Property rights to Infosys Technologies for an unspecified royalty. Infosys is mandated with further developing the software, enhancing its features to interface with other related tools and programs, and increasing applicability in related areas. Autolay was no flash in the pan either. After the success with Autolay, ADA now plans to put another software tool christened “Prana” on the block. ADA hopes proceeds from Prana will drive another wave of development, thus ensuring the sustainability of a huge enterprise.

The Product That Started It All

Autolay is an integrated automated software system for the design and development of 3-D laminated composite components. To make the aircraft lighter, LCA uses (as high as 45 percent) composite materials extensively in its airframe. In addition to their light weight, composite materials are also amenable to tailoring their mechanical properties, thereby providing better performance capabilities. However, the processes of the design and development of laminated composite components is radically different from those used in conventional metal structures. It required a new range of multidisciplinary knowledge and computational techniques.

Autolay was designed to address these composite design and development requirements. The software automates the creation of engineering data required to drive the end-to-end design and manufacturing simulation of laminated composite components. Depending on component design complexity and the extent of automation in the fabrication process, reduction of cycle times of up to 70% can be realized routinely by the use of this software. In realistic terms, this would result in a reduction of a minimum of 6 to 8 months in the design and development cycle time of typical aircraft projects. Apart from aerospace, the software can also be effectively used in the shipbuilding, automotive, recreational, and sports goods industries.

as for the titanium-alloy materials used in the Tejas, the tooling required for machinig them are being provided by Hindustan Machine Tools who also provide some of the most critical jigs and fixtures needed for manufacturing and assembly of the Tejas
 
People. Not everything has to become a dirt-throwing match. In that picture, the LCA looks quite good. Overall, I don't like its design (speaking purely in terms of looks). That is not a crime. People usually dislike the way the Raptor looks, I don't. I'm not sorry about it.

The Indians must be given credit where it is deserved. It is an incredible feat to design a complete airborne weapons system. However, the Indians should stay within reasonable limits and not make claims that defy all logic. That is all I am going to say about that.

Someone should start a thread on the best looking fighters.

niaz sir, yes the requirement have changed that is why from 2001 the electronics in this plane are in open architecture. The current engine will only erve for one squadron. New engine is getting selected. LCA has already been tested with siva pod (laser designator pod). First it was supposed to fire R 60 as WVR missile but after changes in 2003 it has already fired R73. LSP3 will sport the radar (there are conflicting reports that weather it is indigenous MMR or ELTA2032/2052).

New engine RFP is out and let's see which one gets selected (GE 414/ EJ 200).

OOPs. Open Architecture means. are you going to run aircraft on Linux then it is great. Easy to Hack ;). When you put the linux in. please install Snort as Intrusion Prevention System. otherwise aircraft will be vulnerable to zero day attacks
 
Is than the image of a moth sitting on some undone cotton wads?

Interesting that the brain could see what you want it to.
 
In that case Sukhois would be the winners:enjoy:

Sukhoi 27 you mean? I don't think so. It looks quite good, but its too damn curvy. Makes it look very feminine, and fighters are not supposed to look feminine. There are better looking planes (RAPTOR).

Obviosuly you don't understand head and tail of open architecture. Open architecture means that new hardware and software can be added easily. Planes with IPS gr8 never heard of it what you will do when you fly a plane? Browse Internet or what Thank god you are not selected in any air force. Linux is OPEN SOURCE software this does not means it is OPEN ARCHITECTURE and Linux is easy to hack! Are you are running for best nut case award haan.

Stop posting nonsense if you don't understand anything

Nice, thank you for sharing. When do you guys beging production?
